One frequent criticisms of J-20's stealth is the canards, however, nobody has ever criticized F-22's protruding twin rear horizontal stabilizers as degrading RCS or VLO performance. As far as physical protrusion, twin horizontal rear stabilizers are essentially permanently locked canards in the rear of the aircraft, yet F-22 stealth isn't compromised. Neither are canards for J-20 stealth!
"Hurr durr, they stick out of the plane like popsicles sticks"
Now I concede that F-22's twin rear horizontal stabilizers are flush & parallel with the aircraft body, but so are J-20's canards during BVR combat at long-distance and supercruising? If I understand correctly, the canards are activated (non-parallel to body) during high AoA which is essentially WVR where VLO isn't even important anymore.... but they are "locked" in parallel position during BVR long-range where RCS and VLO performance is utmost importance? Just wanted to confirm if the logic is correct because the canard criticism is so damn frustrating.
